350W ATX Gold power supply for modern PCs

This 350 watt ATX unit delivers 80 Plus Gold efficiency for lower power draw and cooler running. It targets builders who need reliable energy for mainstream desktops and workstations. Modern Standby support enables extremely fast wake-from-sleep times and better low-load efficiency. The compact form factor fits standard ATX cases without modification.

Upgrade from older Bronze or unrated units

Replacing an older Bronze or unrated supply with this Gold model cuts waste heat and reduces coil whine through resonant LLC topology with DC-to-DC conversion. The efficiency jump is worth it when electricity costs matter or when a system runs for long periods at low load. Zero RPM fan mode keeps the unit silent during light workloads. Buyers who need more than 350 watts for multi-GPU or high-end CPU configurations should look elsewhere.

Straightforward ATX installation

Installation follows the usual ATX procedure: mount the unit, connect the 24-pin motherboard and CPU power cables, then attach drive and peripheral leads. The fully wired harness means no modular cables to misplace, but it also leaves unused connectors inside the case. Cable stiffness can make routing tight behind the motherboard tray in smaller chassis. Ensure the fan orientation matches your case airflow design for optimal Zero RPM performance.

Perguntas sobre este artigo

What ATX case dimensions does the KHACHIMO PSR350-AN fit?

The unit is a standard ATX power supply, so it mounts in any case with an ATX PSU cut-out and the usual four rear screws.

Which cable should I plug in first when installing the PSR350-AN?

Secure the 24-pin ATX motherboard connector and the CPU power connector before routing any peripheral cables; the non-modular design means all leads are fixed.

Does the 80 Plus Gold fan ever need cleaning?

The Zero RPM mode stops the fan at low and medium loads, reducing dust build-up, but periodic cleaning of the intake grill is still recommended.
